The dimensions for optimal viewing on the platform are universally understood to be 9:16. This vertical format ensures content occupies the full screen of a smartphone in portrait mode, creating an immersive user experience. Videos recorded or edited in other formats may display with black bars, reducing visual impact.
Adhering to the prescribed dimensions is critical for maximizing engagement. Content designed for the intended screen size presents a polished and professional aesthetic, which can significantly enhance user perception and encourage interaction. Furthermore, the ubiquitous nature of smartphones has solidified the vertical format as a standard for short-form mobile video.
